Cisco伪造HSRP导致回路拒绝服务攻击漏洞
Vulnerability Description
IOS是一款由CISCO公司分发的使用在CISCO路由器上的Internet操作系统。Hot Standby Routing Protocol (HSRP)是用于允许多个路由器动态进行相互备份的协议，HSRP协议使用UDP 1985端口进行通信。 CISCO的HSRP协议本身设计问题，可导致本地网络的攻击者进行拒绝服务攻击。 HSRP协议没有严格的安全验证机制，对网络上的路由器通信也没有进行正确的检查，攻击者可以在激活路由器上设置回路接口地址，当通过HSRP协议对虚拟路由器进行通告时，直接采用此回路接口而
